About Ampere-hours
The ampere-hour (Ah) equals exactly 3 600 C and is the universal capacity unit for rechargeable batteries. Lead-acid car batteries are rated 40-100 Ah; EV traction packs use 50-300 Ah cells; industrial forklift batteries exceed 1 000 Ah. Multiplying Ah by nominal voltage gives watt-hours of stored energy. 1 Ah = 3 600 C = 1 000 mAh.
About Elementary charge
The elementary charge (e) is the magnitude of charge on a single proton or electron, defined exactly as 1.602 176 634 × 10⁻¹⁹ C in the 2019 SI revision. It is the quantum of electric charge - the smallest freely occurring charge in nature - and underpins all atomic and subatomic physics. A current of 1 A corresponds to 6.241 509 × 10¹⁸ elementary charges flowing per second.
